Biotherm Blue Theraphy Night Cream

What you are looking at is Biotherm Blue Theraphy Night Cream, a skincare product in a 50 ml size. Skincare works on a schedule of weeks rather than days — most formulas need consistent use before there is anything to see. Patch test on the inner arm or along the jaw first, especially if you are already using retinoids, acids or vitamin C. Discounted listings come and go, and rarely at the same shop twice. Follow with SPF in the morning: plenty of active ingredients leave skin more sensitive to sunlight than usual. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
